ABSTRACT:
A low-friction, boat-type, cold-formed rocker arm is provided. The rocker arm is of generally U-shaped configuration in transverse cross section throughout most of its length. An intermediate portion of the rocker arm has a concave interior surface extending there-across with a central opening through which a shank of a pedestal extends. One end portion of the rocker arm has a concave recess facing downwardly to receive the upper end of a push rod. The other end portion of the rocker arm has a rectangular opening in the bottom thereof. An axle extends between side walls of the rocker arm above the rectangular opening and a roller is rotatably mounted on the axle and has a circumferential portion exposed at the rectangular opening. The roller engages an end of a valve stem with rolling, rather than sliding, contact, resulting in lower friction during operation of the rocker arm.
